STD XII – CHEMISTRY
CHEMICAL THERMODYNAMICS
UNIT -2
TR. JULIE TONY
, NATURE OF HEAT AND WORK
In thermodynamics, work is done
when a gas expands or contracts W = P.V
against an external opposing force. 𝒇
= 2. V
ie, it is pressure – volume type. d
𝒇 3
W = P.V = . d
But P = f/A
d2
If d is the distance, then A = d2
and volume V = d3 W= f. d…
